is it possible?

boymomforever 💙💙🤰 • Mother of five angel babies, a happy and healthy 4yo boy & a 1.5yo boy & last baby and BOY #3 due June 20 ‘23 💙
I got 3 faint positives on frer 2 one day, 1 the next .. got blood work done after & its negative. 
Is it possible that I could still be pregnant? 
How could I get positive urine if the blood is negative. 
Sooooo confused :(
